Etymology 2Edit

In allusion to the character Tin Man from the Land of Oz, who lacked a heart.


tinman (uncountable)

  1. (genetics) A master gene in the fruit fly Drosophila melanogaster, whose absence causes the fly to develop without a heart.
    • 2000, Carl Zimmer, “The Hidden Unity of Hearts”, in Natural History[1], volume 109, number 3, pages 56-61:
      Tinman belongs to a special class of genes. [...] But some genes make proteins that control other genes. Some act like master switches, triggering many different genes to work together to build a structure. Tinman is one such “master gene” for the fruit fly.
